This book reveals the science and beauty of Mammoth Cave, the world's longest cave, which has played an important role in the natural sciences. It offers a comprehensive and interdisciplinary treatment of the cave, combining insights from leading experts in fields ranging from archeology and cultural history to life science and geosciences. The first animals specialized for cave life in North America, including beetles, spiders, crayfish, and fish, were discovered in Mammoth Cave in the 1840s. It has also been used and explored by humans, including Native Americans, who mined its sulfate minerals and later African-American slaves, who made a map of the cave. More recent stories include 'wars' between commercial cave owners, epic exploration trips by modern cave explorers, and of course tourism. The first section of the book is an extensive description including maps and photos of the cave, its basic structural pattern, and how it relates to the surface landscape. The second section covers the human history of utilization and exploration of the cave, including mining, tourism, and medical experiments. Cave science is the topic of the third section, including geology, hydrology, mineralogy, climatology, paleontology, ecology, biodiversity, and microbiology. The fourth section looks to the future, with an overview of environmental issues facing Mammoth Cave managers. The book is intended for anyone interested in caves in general and Mammoth Cave in particular, experts in one discipline seeking information about other areas, and researchers and students interested in the many avenues of pursuit possible in Mammoth Cave.

Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influences our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most important, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including air quality at the Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical - not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks", observe Halvorson and Davis, "perhaps we can learn to save the world".

This volume has its roots in the distant past of more than 20 years ago, the International Hydrologic Decade (IHD), 1964-1974. One of the stated goals of the IHD was to promote research into groundwater situations for which the state of knowledge was hopelessly inadequate. One of these problem areas was the hydrology of carbonate terrains. Position papers published early in the IHD emphasized the special problems of karst; carbonate terrains were supposed to receive a substantial amount of attention during the IHD. There were indeed many new contributions from European colleagues but, unfortunately, in the United States the good intentions were not backed up by much in the way of federal funding. Some good and interesting work was published, particularly by the U. S. Geological Survey (USGS), but in the academic community the subject languished. About this same time the Cave Research Foundation (CRF), organized in 1957 to promote the systematic exploration, survey, and scientific study of the great cave systems of Mammoth Cave National Park, was casting about for a broader scope for its research activities. Up until that time, CRF research had been largely restricted to detailed mineralogical and geological investigations within the caves, with the main part of the effort concentrated on exploration and survey. The decision to investigate the hydrology required a certain enlargement of vision because investigators then had to consider the entire karst drainage basin rather than isolated fragments of cave passage.
